RTI R - audio Transaction Identifier

In GPRS the Radio Transaction Identifier is used to group the downlink RLC / MAC (Radio Link Control / Medium Access Control) control blocks that make up an RLC/MAC control message and identifies the segmented control message sequence with which the downlink RLC/MAC control block is associated. The RTI field is five bits in length with range 0 to 31.
